Inmarsat High Gain Antenna
The AMT-700 is typically housed under
a tail-mounted radome, but can also
be mounted at several locations on
the fuselage.
The use of an integrated ACU enables
greater flexibility during installation and
reduces the number of units required.
ARINC 781 DLNA interfaces allow
this system to be used with any
manufacturer's SwiftBroadbandapproved HPA or terminal.
The eNfusion® AMT-700 is a complete

ARINC 781 High Gain Antenna (HGA).
provide greater flexibility for installation.
The antenna is used to receive and
The antenna’s technology and design
transmit voice and data from aircraft via
the Inmarsat satellite network, and
supports multi-channel SwiftBroadband
(Class 6 services).
Form Factor
The AMT-700 is a mechanically steered
Inmarsat antenna that meets ARINC 781
(U.S. patent pending) result in the highest
gain of any Inmarsat mechanical high
gain antenna – achieving greater than
13.5dBic over 100 percent of the Inmarsat
coverage volume.
